The idea of informing network owners’ abuse departments about malicious incidents is not new, but still a very effective and the most inexpensive way of letting people in charge know that there is something wrong in their own network (http://www.ietf.org/rfc/rfc2142.txt). Actually, it is one of the best methods to help enforce security on the Internet in a self-regulating way.
We have a saying in M3AAWG: What goes on at M3AAWG, stays in M3AAWG. Anyone who has attended one of our meetings knows that we work hard to create an environment of respect and confidentiality. We see our organization as a forum where the anti-abuse industry can come together to address both current and evolving issues in a candid, productive dialogue.
